Method and system for optimizing antenna feeder parameters

The invention discloses a method and a system for optimizing antenna feeder parameters, which are used for joint automated optimization of a plurality of antenna feeder parameters in a TD-SCDMA (Time Division-Synchronization Code Division Multiple Access) network, ensuring a whole optimization effect and improving wireless network quality. The optimization method comprises the following steps of: simulating a wireless network environment on the basis of wireless network base data and road test data, and positioning a coverage and interference problem region in the wireless network environment according to the road test data; selecting a problem cell in a plurality of cells included in the positioned coverage and interference problem region, and adjusting each antenna feeder parameter according to the preset optimal condition; and assessing a preset network coverage and interference index on the basis of current adjustment for each antenna feeder parameter, and when an assessed value of the network coverage and interference index in the coverage and interference problem region reaches an expected target value, the optimization of the antenna feeder parameters can be carried out according to the adjusted antenna feeder parameters.
